Disassembly and Excitation Method: Before use, check for leaks at the connections. Apply soapy water to check for leaks. Only proceed with the experiment after confirming there are no leaks. After confirming the pressure reducing valve is closed (T adjusting screw loose), open the main valve of the cylinder counterclockwise and observe the high-pressure gauge reading. Then, open the small valve on the left side of the pressure reducing valve counterclockwise...

Precautions: 1. The room must be well-ventilated to ensure the hydrogen content in the air does not exceed 1% (by volume). The indoor air exchange rate should not be less than three times per hour, and the local ventilation rate should not be less than seven times per hour.
